I cannot reproduce this one: my tooltip.el has this:
(defcustom tooltip-frame-parameters
'((name . "tooltip")
(internal-border-width . 2)
(border-width . 1))
"Frame parameters used for tooltips.
If `left' or `top' parameters are included, they specify the absolute
position to pop up the tooltip.
Note that font and color parameters are ignored, and the attributes
of the `tooltip' face are used instead."
:type 'sexp <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
:group 'tooltip)
According to Git, this line was there for the last 18 years.

See above: the doc string of tooltip-frame-parameters says font and
color parameters are ignored.
